Hokuro is a guardsman of the Bosse Kingdom and one of the few at court who is fluent in sign language. He is very loyal to Prince Bojji. Hokuro is a deeply loyal, responsible person, unwilling to shirk his duties even when they directly endanger his life. He also appears to be a very level-headed, reasonable person, which gives him unique insight into some of the bigger, more ostentatious personalities of the Bosse Kingdom. Hokuro's beloved mother appears to have been deaf, making him one of the few guardsmen in the Bosse Kingdom who knows sign language. A chance encounter with Bojji while visiting his mother's grave seems to have given Hokuro a deep respect and admiration for the young prince.
